PU Static Seals
Technical data

| SSV-A406 |  | TPU | 95 SH A | -30 °C to +110 °C | ≤500 | ≤1.0 m/s |
PU Static seals SSV - A406
Designed to replace the O-ring and the support ring combination in static applications, this double-acting static seal for outer sealing, by its design, enables to eliminate the rotation problem encountered in O-ring assemblies. It can be produced in accordance with standard O-ring grooves. The difficulties faced during an o-ring assembly such as twisting, ripping was solved with this design. It can be used without a back-up ring at high pressures. Due to the material, it does have good wear resistance to extrusion and shows good sealing performance in double acting applications.
ADVANTAGES
- Able to work in high pressures Interchangeable for o-rings or o-ring with back-up rings
- Usable for rough surface finish
- Easy and secure installation
- High wear, abrasion and extrusion resistance
- No need for additional back-up ring
APPLICATIONS
Any hydraulic applications in which an O-ring is required.

INSTALLATION
Easily assembled by hand. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
